• NEVER operate the chainsaw when fatigued, ill or under the influence of medication, alcohol or drugs.
• ALWAYS USE safety equipment; appropriate footwear, eye protection, ear protection, head protection, trousers and gloves.
• ALWAYS keep the chainsaw sharp and well maintained. A dull chain causes vibration which can damage the machine.
• ALWAYS inspect the chainsaw before use for worn, loose or damaged parts.
• ALWAYS carry the chainsaw with the engine stopped, with the guide bar and chainsaw facing to the rear.
• DO NOT start the engine within 3m of the fuelling point.
• REMOVE all sources of sparks and flames before mixing and pouring fuel.
• DO NOT let anyone near the chainsaw when starting or cutting. Keep everyone, especially children, away from the work area.
• KEEP all parts of your body away from the saw chain when the engine is running.
• DO NOT start cutting until you have a clear cutting area and a secure footing.
• NEVER cut trees or foliage in high wind, bad weather or when there is poor visibility.
• GUARD AGAINST kickback. Kickback can cause loss of control.
• DO NOT operate the chainsaw with one hand. ALWAYS Hold the chainsaw firmly with both hands.
• BE ALERT for the phenomena of "skating" and "bouncing".
• BE CAUTIOUS not to lose balance of your body due to "drop" at the end of a cut.
• ALWAYS keep the handles dry, clean and free of oil and fuel mixture.
• ALWAYS shut o the engine before putting the chainsaw down.
• ONLY OPERATE the chainsaw outdoors or in well ventilated areas.

FOR SAFE OPERATION
FOR SAFE OPERATION
GLOVES
Gloves should be worn where appropriate.
HEARING PROTECTION
Hearing protection should be worn to prevent
damage to your ears. Ensure your hearing
protection provides adequate noise reduction.
EYE PROTECTION
Approved eye protection should be worn at all
times during operation.
BOOTS
Wear sturdy, non-slip boots.
CLOTHING
Appropriate clothing should be worn during
operation. Ensure clothing is made of strong
fabric and is not baggy or loose.
IMPORTANT
• Never operate a chain saw when you are fatigued, ill, or upset, or
under the influence of medication that may make you drowsy, or if
you are under the influence of alcohol or drugs - risk of accident!
• Use safety footwear, snug fitting clothing and eye, hearing and head
protection during use.
• Keep the saw chain sharp and the saw, including the AV system,
well maintained. A dull chain will increase cutting time, and pressing
a dull chain through wood will increase the vibrations transmitted
to your hands. A saw with loose components or with damaged or
worn AV buers will also tend to have higher vibration levels.
• Always use caution when handling fuel. Wipe up all spills and then
move the chainsaw at least 3m from the fuelling point before
starting the engine - risk of fire!
• Eliminate all sources of sparks or flame (i.e. smoking, open flames,
or work that can cause sparks) in the areas where fuel is mixed,
poured, or stored - risk of fire!
• Do not smoke while handling fuel or while operating the chain saw
- risk of fire!
• Do not allow other persons to be near the chain saw when starting
or cutting. Keep bystanders and animals out of the work area.
Children, pets and bystanders should be a minimum of 10m away
when you start or operate the chainsaw - risk of accident!
i• Never start cutting until you have a clear work area, secure
footing, and a planned retreat path from the falling tree - risk of
accident!
• Always hold the chain saw firmly with both hands when the
engine is running. Use a firm grip with thumb and fingers
encircling the chain saw handles.
• Keep all parts of your body away from the saw chain when the
engine is running - risk of accident!
• Before you start the engine, make sure the saw chain is not
contacting anything - risk of accident!
• Always carry the chain saw with the engine stopped, the guide
bar and saw chain to the rear, and the muler away from your
body. Always inspect the chain saw before each use for worn,
loose, or damaged parts. Never operate a chain saw that is
damaged, improperly adjusted, or is not completely and secure-
ly assembled. Be sure that the saw chain stops moving when
the throttle control trigger is released. All chain saw service,
other than the items listed in the Owner’s Manual, should be
performed by competent chain saw service personnel. (e.g if
improper tools are used to remove the flywheel, or if an improper
tool is used to hold the flywheel in order to remove the clutch,
structural damage to the flywheel could occur which could sub-
sequently cause the flywheel to disintegrate.)
• When transporting your chain saw, make sure the appropriate guide
bar scabbard is in place.
• Always shut o the engine before setting it down.
• Use extreme caution when cutting small size brush and sap-
lings because slender material may catch the saw chain and be
whipped toward you or pull you o balance - risk of accident!
• When cutting a limb that is under tension, be alert for spring-
back so that you will not be struck when the tension in the wood
fibers is released.
• Never cut in high wind, bad weather, when visibility is poor or in
very high or low temperatures. Always check the tree for dead
branches which could fall during the felling operation. Keep the
handles dry, clean and free of oil or fuel mixture.
• Operate the chain saw only in well ventilated areas. Never start
or run the engine inside a closed room or building and potential-
ly explosive atmosphere. Exhaust fumes contain dangerous car-
bon monoxide - risk of fatal injury from breathing toxic fumes!
• Do not operate the chain saw in a tree unless specially trained to.
• Guard against kickback. Kickback is the upward motion of the guide
bar which occurs when the saw chain at the nose of the guide bar
contacts an object. Kickback can lead to dangerous loss of control
of the chain saw.
• Sawdust, fumes, smoke and lubrication oil mist may be produced
while using the machine may be hazardous to health. If dust is gen-
erated, wear a dust mask.

FOR SAFE OPERATION FOR SAFE OPERATION
• Never touch the cover, guide bar, saw chain or nut with bare hands
while the engine is in operation or immediately after shutting down
the engine. Doing so could result in serious burns because of high
temperature.
KICKBACK SAFETY PRECAUTIONS
• Kickback may occur when the nose or tip of the guide bar touches
an object, or when the wood closes in and pinches the saw chain
in the cut. Tip contact in some cases may cause a lightning fast
reverse reaction, kicking the guide bar up and back towards the
operator. Pinching the saw chain along the top of the guide bar
may push the guide bar rapidly back towards the operator. Either
of these reactions may cause you to lose control of the saw, which
could result in serious personal injury.
• When the chainsaw fails to dig in during a cut, the guide bar can
begin hopping or dangerously skidding along the surface of the log
or branch, possibly resulting in the loss of control of the chainsaw.
To prevent or reduce skating or bouncing, hold the chainsaw with
two hands and make sure the saw chain establishes a groove for
cutting.
• Do not rely exclusively on the safety devices built into your saw.
• With a basic understanding of kickback you can reduce or
eliminate the element of surprise. Sudden surprise contributes to
accidents.
• Keep a good grip on the saw with both hands, the right hand on
the rear handle, and the left hand on the front handle, when the
engine is running. Use a firm grip with thumbs and fingers en-
circling the chain saw handles. A firm grip will help you reduce
kickback and maintain control of the saw.
• You cannot control reactive forces and you may lose control of
the saw, which can result in skating and bouncing of the bar
along the limb or log.
i
REDUCING THE RISK OF KICKBACK
• Work cautiously and methodically
• Hold the chain saw firmly with both hands and maintain a secure
grip
• Always cut at full throttle
• Be aware of the location of the guide bar nose
• Do not cut with the guide bar nose
• Be especially careful with small, tough limbs, undergrowth and
oshoots – the saw chain may become caught in them
• Never cut several limbs at once
• Do not lean too far forward
• Do not cut above shoulder height
• Use extreme caution when reentering a previous cut
• Do not attempt plunge cuts if you are not experienced in this
cutting technique
• Be alert for shifting of the log or other forces that may cause the
cut to close and pinch the chain
• Always cut with a correctly sharpened, properly tensioned saw
chain – the depth gauge setting must not be too large
• Use low-kickback saw chains as well as narrow-radius guide
bars
HANDLING FUEL
• The engine of our product is designed to run on a mixed fuel, which
contains highly flammable gasoline. Never store cans of fuel or refill
the tank of the unit in any place where there is a boiler, stove, wood
fire, electrical sparks, welding sparks, or any other source of heat or
fire which might ignite the fuel.
• Never smoke while operating the unit or refilling its fuel tank.
• When refilling the tank, always turn o the engine and allow it to
cool down. Take a careful look around to make sure that there are
no sparks or open flames anywhere nearby before refuelling.
• Wipe spilled fuel completely using a dry rag if any spillage occurs
during refuelling.
• After refuelling, screw the fuel cap back tightly onto the fuel tank
and then carry the unit to a spot 3m or more away from where it
was refuelled before turning on the engine.

FOR SAFE OPERATION
EFFECTS OF VIBRATION
Vibrationwhite finger(VWF) is an injury triggered by continuous use of
vibrating hand-held machinery.
If you continue to use high-vibration tools these symptoms will probably
get worse, for example:
• the numbness in your hands could become permanent and you
won’t be able to feel things at all;
• you will have diiculty picking up small objects such as screws or
nails;
• Vibration White Finger (VWF) could happen more frequently and
aect more of your fingers.
PROTECTING YOUR BODY FROM VIBRATION
Please observe the following matter, in order to protect the health of
your body.
• Always use the right tool for each job (to do the job more quickly
and expose you to less hand-arm vibration).
• Check tools before using them to make sure they have been proper-
ly maintained and repaired to avoid increased vibration caused by
faults or general wear.
• Make sure cutting tools are kept sharp so that they remain eicient.
• Reduce the amount of time you use a tool in one go, by doing other
jobs in between.
• Avoid gripping or forcing a tool or workpiece more than you have to.
• Store tools so that they do not have very cold handles when next
used.
Encourage good blood circulation by:
• Keeping warm and dry (when necessary, wear gloves, a hat, water-
proofs and use heating pads if available);
• Giving up or cutting down on smoking because smoking reduces
blood flow;
• Massaging and exercising your fingers
DISPOSAL
When disposing your machine, fuel or oil for the machine, be sure to
allow your local regulations.

TRANSPORTING THE CHAINSAW
• Always stop the engine before putting a chainsaw down or carrying
it. Carrying a chainsaw with the engine running is extremely dan-
gerous.
• Accidental acceleration of the engine can cause the chain to
rotate.
• During operation, the muler and the material around it reach
extremely high temperatures. Avoid touching the hot muler, you
could receive serious burns.
• BY HAND: When carrying your saw by hand, the engine must
be stopped and the saw must be in the proper position. Grip the
front handle and place the muler away from the body.
The chain guard (scabbard) should be over the chain and the
guide bar, which should point backwards. When carrying your
saw, the bar should be behind you.
• BY VEHICLE: When transporting in a vehicle, keep chain and
bar covered with the chain guard. Properly secure your saw to
prevent it moving around during transit, which in turn can cause
fuel spillage and damage to the saw.

STARTING THE ENGINE
Make sure there is suicient fuel and oil inside the
chainsaw. Fuel should be fresh unleaded petrol mixed
with 2-stroke oil at a ratio of 25:1.
Example: 1 litre of unleaded petrol mixed with 40ml of
2-stroke oil.
If your chainsaw is fitted with a fuel primer press the
bulb six times. If the bulb is still not full of fuel please
repeat the process.

CHAIN BRAKE
The chain brake is a device which stops the chain should the
chainsaw recoil due to kickback. Normally, the brake is
activated automatically by inertial force, however it can also be
activated manually by pressing the brake lever forward / away
from you.
TO RELEASE THE BRAKE
Release the chain brake by pulling the handle towards you
when holding the saw. Some force maybe required to disen-
gage the brake. This is to prevent the accidental releasing of
the brake while in use.
TO ENGAGE THE BRAKE
Engage the brake by pushing the brake handle away from you
when holding the saw. The brake is spring loaded so after some
initial force the brake will move forward on its on momentum.
If the brake operates during use immediately release the throt-
tle to reduce engine speed and when deemed safe release the
brake and resume use.
Continuous operation while the brake is
engaged will generate excessive heat, which
can melt the brake assembly and damage
the clutch.
BRAKE DISENGAGED
BRAKE ENGAGED
CHAIN BRAKE
CORRECT USE OF CHAIN BRAKE
• At all times, confirm whether the brake works properly before
each task.
• If the chain brake is clogged with wood chips the eectivness of
the brake is diminshed.
• Always keep the device clean.
• Do not increase engine revolutions while the chain brake is
engaged.
• Chain brake is used in emergencies.
• Do not use it unless absolutely necessary.
• After starting the engine, release the brake immediately.
• Never test the brake in an area where petrol fumes are present.
The following may interfere with the brake's ability to protect the
operator:
• Saw wrongly held too close to operator's body.
• Kickback time may be too fast even for a perfectly maintained brake
to work in time.
• The operator's hand may not be in position to contact the hand
guard. Brake will not be tripped.
• Lack of proper maintenance lengthens the brake's stopping time,
making it less eective.
• Dirt, grease, oil, pitch, etc. getting into the working parts of the
mechanism may lengthen the stopping time.
• Wear and fatigue of the activating brake spring, and wear of the
brake / clutch drum and pivot points may lengthen the brake's stop-
ping time.
• A damaged hand guard and lever may render the brake inoperative.
Always check that chain brake works properly before use.

26 27
CHAIN BRAKE OIL FLOW
ADJUSTING THE OIL FLOW
Chain and bar lubricant promotes smooth operation by keeping
the chain clean and free-running on the guide bar. Oil will lubri-
cate the chain thereby preventing the chain from overheating
and rusting.
In order to prevent excessive wear on the chain and to avoid oil
waste always check and, when necessary, adjust the oil flow
from the saw.
By adjusting the oil pump on the underside of the saw, the flow
of oil can be increased or decreased using a small, flat-head
screwdriver. Turning the screw clockwise will decrease the oil
flow and counter clockwise will increase the oil flow.
During use you will see the oil falling onto the chain from the oil
port. The higher the engine speed the quicker the oil will flow.
Excessive turning of the oil adjustment
screw can cause premature damage to the
oil pump. Do not force the screw past it's
furthest point.
TESTING THE BRAKE
1. Start the engine.
2. Place the chain saw on the ground.
3. Hold the rear handle with your right hand and the front handle
with your left hand.
4. Accelerate the engine to high speed by using the throttle trigger.
5. Operate the chain brake by turning your left wrist against the
front hand guard whilst gripping the front handle.
6. The chain should stop immediately.
7. Release the throttle trigger.
If the chain does not stop immediately contact Parker Products
TESTING THE AUTOMATIC BRAKE
The automatic chain brake stops the chain when kickback occurs.
When checking the operation of the non-manual chain brake, use a
soft surface substance like wood to provide the impact so the saw
chain is not damaged.
To make sure that the non-manual chain brake operates properly,
proceed as follows:
1. Stop the engine of the chain saw.
2. Hold the rear handle with your right hand and the front handle
with your left hand (grip them lightly), so that the guide bar is
approxiamtely 55cm o the ground.
3. Softly let go with left hand from the front handle while gripping
lightly with your right hand, and let the end of the guide bar hit
against the wood or similar placed below so that the machine
receives an impact.
4. The impact should engage the chain brake.

CLEANING THE OIL FILTER
1. Remove the oil filler cap
2. Using a wire hook carefully remove the oil filter as illustrated.
3. Once removed clean the oil filter in petrol and replace.
4. If possible remove any dirt and debris inside the reservoir.
5. When reinstalling the oil filter back into the tank make sure the
filter sits at the front right corner of the tank.
CLEANING THE FUEL FILTER
1. Remove the fuel filler cap.
2. Using a wire hook remove the filter through the filler port
as illustrated.
3. Disconnect the filter and wash in petrol or replace where
necessary.
4. Ensure that, whilst the filter is disconnected, no debris or
fibres from the filter enters the fuel pipe.
ADJUSTING THE CARBURETTOR
ADJUSTING THE CARBURETTOR
The carburettor on your saw has been factory set but may
require some minor adjustments due to a change in operat-
ing conditions. Before adjustment, make sure that the air/fuel
filters are clean and the fuel is properly mixed.
It is recommended that adjustments are done when the chain-
saw is warm and fully assembled.
T- This controls the engine speed at idle. If set too low the
saw will stall. If set too high the chain will move. The saw chain
should not move at engine idle speed, otherwise serious injury
may result.
L- Low speed adjustment screw (this is the low speed jet).
This is the adjustment that controls the air/fuel mixture at idle.
Adjust this screw too rich and the chainsaw will stall at idle
speed. Adjust this screw too lean and the engine will race or
surge. An extremely lean adjustment will also cause the engine
to flood.
H- High speed adjustment screw (this is the high speed jet).
This is the adjustment that controls the air/fuel mixture at high
RPMs. Adjust this screw too rich and the chainsaw will stall,
too lean and it will over rev.
Never adjust the carburettor more than 1/4 turn in either direc-
tion without first testing the saw. To reset your carburettor to
factory settings fully close both the L and H screws by turning
clockwise and then anti clockwise 1 1/2 turns.

FUEL INSTRUCTIONS
RECOMMENDED MIXING RATIO GASOLINE 25 : OIL 1
• Gasoline is very flammable. Avoid smoking or bringing any flame or
sparks near fuel. Make sure to stop the engine and allow it cool be-
fore refuelling the unit. Select outdoor bare ground for fuelling and
move at least 3m (10 ft) away from the fuelling point before starting
the engine.
• The engines are lubricated by oil specially formulated for air-
cooled 2-cycle gasoline engine use.
• Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.
• Exhaust emission are controlled by the fundamental engine
parameters and components (eq., carburation, ignition timing
and port timing) without addition of any major hardware or the
introduction of an inert material during combustion
• These engines are certified to operate on unleaded gasoline
• If you use a gasoline of a lower octane value than prescribed,
there is a danger that the engine temperature may rise and an
engine problem such as piston seizing may consequently occur.
• Unleaded gasoline is recommended to reduce the contamination
of the air for the sake of your health and the environment.
• Poor quality gasoline or oils may damage sealing rings, fuel lines
or fuel tank of the engine.
HOW TO MIX FUEL
Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be mixed.
2. Put some of the gasoline into a clean, approved fuel container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for at least one
minute. As some oils may be diicult to GB 1 agitate depending
on oil ingredients, suicient agitation is necessary for the engine
to last long. Be careful that, if the agitation is insuicient, there
is an increased danger of early piston seizing due to abnormally
lean mixture.
5. Put a clear indication on the outside of the container to avoid
mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy identifica-
tion
FUEL INSTRUCTIONS
FUELLING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a dustless
place
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel spillage
around the unit
• Select flat and bare ground for fuelling.
• Move at least 10 feet (3 meters) away from the fuelling point be-
fore starting the engine.
• Stop the engine before refuelling the unit. At that time, be sure to
suiciently agitate the mixed gasoline in the container
FOR YOUR ENGINE LIFE, AVOID:
• FUEL WITH NO OIL (RAW GASOLINE) - It will cause severe
damage to the internal engine parts very quickly.
• GASOHOL - It can cause deterioration of rubber and/ or plastic
parts and disruption of engine lubrication.
• OIL FOR 4-CYCLE ENGINE USE - It can cause spark plug foul-
ing, exhaust port blocking, or piston ring sticking.
• Mixed fuels which have been left unused for a period of one
month or more may clog the carburettor and result in the engine
failing to operate properly.
• In the case of storing the product for a long period of time, clean
the fuel tank after rendering it empty. Next, activate the engine
and empty the carburettor of the composite fuel.
• In the case of scrapping the used mixed oil container, scrap it
only at an authorized repository site.
